Graphics chip maker Nvidia on Friday announced seven new GeForce 400M series graphics cards for notebooks, which could provide parallel-processing capabilities to accelerate Web browsing and 3D image rendering.

Per Macworld, Microsoft’s Internet Explorer, Mozilla’s Firefox and Google’s Chrome have either implemented or will soon include the capability to offload tasks like rendering of HTML 5 or Flash video content to graphics processors. Nvidia’s new GeForce graphics cards will be faster at processing those tasks than CPUs, which should make Web browsing snappier.

The new graphics cards will be around 40% faster than the earlier 300M series at execution of tasks, said Ken Brown, an Nvidia spokesman.

While the CPU remains at the center of running tasks, developers are writing applications to harness the parallel-processing capabilities of graphics processors to speed up applications, said Dean McCarron, principal analyst at Mercury Research.

“That’s one of the changes with the new browsers, is they support that capability,” McCarron said.

Notebooks with Intel’s latest Core processors already have a graphics processor integrated in one chip next to the CPU. However, discrete GPUs have a faster and wider pipe to run applications, McCarron said.

Still, graphics processors can draw more power than CPUs or integrated graphics, which can affect battery life of notebooks. Nvidia’s graphics cards support new switchable technology called Optimus, where specific tasks like video rendering can be seamlessly switched between the CPU and GPU. The GPU kicks in only when needed, preserving the notebook’s battery life.

Nvidia declined to comment on the exact power drawn by the new graphics cards, citing company policy. In recent years the company has taken charges for faulty dies and weak packaging material used in its graphics chips that led to notebooks overheating. Those issues have been resolved for a while, Brown said.

“Nvidia GPUs are made with a different manufacturing substrate to prevent chips from experiencing thermal issues over time. Our GPUs run in the tolerance level of their specification and the notebook chassis design constraints,” Brown said.

More laptops are shipping with discrete GPUs as users look for stronger multimedia capabilities, McCarron said. Nvidia will be trying to extend its presence in the market with the new products, and it will have to compete with rival Advanced Micro Devices, which already offers Radeon HD notebook graphics cards.

The new offerings include the GeForce GT 415M, GT 420M, GT 425M, GT 435M, GT 445M, and the faster GTX 460M and GTX 470M graphics cards. The cards will be available only through the PC makers, and Nvidia did not comment on when the notebooks would become available. The graphics cards will be offered through PC makers including Acer, Asus, Dell, Lenovo, Samsung and Toshiba.

Individual pricing for the graphics cards and whether or not the cards would eventually find their way to Apple’s notebook products were not disclosed.

The good thing about mobile laptop desks is people can read books in their bed whenever they feel like. Many people made it a habit to read books in their bed until they fall asleep. It helps them calm their nerves and ease stress. If they are not comfortable with the way their body is positioned then they will not be able to rest their body. If their back is not properly angled in the right position then it can trigger muscle pain. Mobile laptop desks give an excellent support to the consumer by making the desk adjust to the people’s need and not the other way around.
